A Double Barrier Technique with Hydrotalcites for Pb Immobilisation from Electric Arc Furnace Dust
Lozano Lunar, Angélica; Fernández Ledesma, Enrique; Romero Esquinas, Álvaro; Jiménez Romero, José Ramón; Fernández Rodríguez, José María (MDPI, 2019)A new line of mortars incorporating hydrotalcites was developed. This research article shows the results of a study of a double barrier technique (DBT) for Pb immobilisation from electric arc furnace dust (EAFD) in mortars ... -
Effect of the Composition of Mixed Recycled Aggregates on Physical–Mechanical Properties
López Uceda, Antonio; Fernández Ledesma, Enrique; Salas-Morera, Lorenzo; Jiménez, José Ramón; Suescum-Morales, David (MDPI, 2021)Recycled aggregates (RA) from construction and demolition waste are an alternative to natural aggregates in the construction sector. They are usually classified according to their composition. The main constituent materials ... -
Feasible use of colliery spoils as subbase layer for low-traffic roads
Suescum-Morales, David; Romero Esquinas, Álvaro; Fernández Ledesma, Enrique; Fernández, José M.; Jiménez, José Ramón (Elsevier, 2019)The aim of this paper is to characterise, both physically and chemically, the colliery spoils of Pozo San José, located in the Guadiato Valley (Córdoba, Spain), and evaluate their possible use as unbound materials or as ... -
Functional and structural parameters of a paved road section constructed with mixed recycled aggregates from non-selected construction and demolition waste with excavation soil
Tavira, Javier; Jiménez, José Ramón; Ayuso Muñoz, Jesús; Sierra, María José; Fernández Ledesma, Enrique (Elsevier, 2018)This paper evaluates the lab and in situ mechanical properties of non-selected mixed recycled aggregates from construction and demolition waste (CDW) used as base and subbase unbound materials. Excavation materials are ... -
Mechanical behaviour of self-compacting concrete made with non-conforming fly ash from coal-fired power plants
Romero Esquinas, Álvaro; Fernández Ledesma, Enrique; Otero, R.; Jiménez, José Ramón; Fernández, José María (Elsevier, 2018)Currently, global sustainability depends on achieving integrated productivity in all economic sectors, making it possible to respond to the environmental challenges facing humanity at present. With the dual objective of ... -
Performance of Sustainable Mortars Made with Filler from Different Construction By-Products
López Uceda, Antonio; Fernández Ledesma, Enrique; Jiménez, José Ramón; Fernández Rodríguez, José María (MDPI, 2022)One way to contribute to sustainability in the construction sector is through the incorporation of construction by-products from their own activities. This work intends to extend the possibilities for enhancement of these ... -
Real-scale study of a heavy traffic road built with in situ recycled demolition waste
Tavira, Javier; Jiménez, José Ramón; Fernández Ledesma, Enrique; López Uceda, Antonio; Ayuso Muñoz, Jesús (Elsevier, 2020)This real-scale study carries out a research of the behaviour of building demolition wastes in a road with high intensity traffic. A mobile recycling plant treated in situ the demolition wastes from 105 single-family homes. ... -
Recycling screening waste and recycled mixed aggregates from construction and demolition waste in paved bike lanes
Tavira, Javier; Jiménez, José Ramón; Ayuso Muñoz, Jesús; López Uceda, Antonio; Fernández Ledesma, Enrique (Elsevier, 2018)This research conducts a full-scale study on the use of recycled mixed aggregates from construction and demolition waste and its screening waste in an experimental bike lane. The subgrade and the natural and recycled ... -

The Effect of Acanthocardia tuberculata Shell Powder as Filler on the Performance of Self-Compacting Mortar
González-Caro, Ágata; Merino-Lechuga, Antonio Manuel; Fernández Ledesma, Enrique; Fernández Rodríguez, José María; González-Jiménez, José R.; Suescum-Morales, David (MDPI, 2023)In this research, the feasibility of using Acanthocardia tuberculata shell waste from the canning industry in the manufacturing of self-compacting mortar (SCM) was tested. The seashells were finely ground to be used as ... -
The role of pH on leaching of heavy metals and chlorides from electric arc furnace dust in cement-based mortars
Fernández Ledesma, Enrique; Lozano Lunar, Angélica; Ayuso Muñoz, Jesús; Pérez Galvín, Adela; Fernández, José María; Jiménez, José Ramón (Elsevier, 2018)Electric arc furnace dust (EAFD) presents a pollution hazard due to its heavy metal leachability. Its characterization is essential for recovery or disposal in hazardous waste landfills. The present work discusses the ... -
The role of powder content of the recycled aggregates of CDW in the behaviour of rendering mortars
Ferreira, Ruan L. S.; Anjos, Marcos A.S.; Nóbrega, Andreza K.C.; Pereira, Jéssyca E.S; Fernández Ledesma, Enrique (Elsevier, 2019)In recent years, the number of studies on the incorporation of recycled aggregate (RA) into mortars has grown considerably. However, mixed recycled aggregate (MRA) is investigated on a much smaller scale due mainly to its ...
